At Calcutta Medical College he was so esteemed by his professors that in the second year of his course he was invited by them to deliver a series of lectures on optics to his fellow students, a task he performed honourably.

He had a brilliant career at that college, where, besides winning several scholarships, he passed the final examination in 1860 with the highest honours in medicine, surgery and midwifery.

He was influenced by reading William Morgan's The Philosophy of Homeopathy, and by interaction with Rajendralal Dutt, a leading homoeopathic practitioner of Calcutta.

In a meeting of the Bengal branch of the British Medical Association, he proclaimed homoeopathy to be superior to the "Western medicine" of the time.

[1] In the course of his career, he treated several notable persons of those days, including the author Bankimchandra Chattopadhyay, the ascetic Ramakrishna, the Maharaja of Tripura and others.

He planned for an association that would be funded, run, and managed by native Indians, with the aim of turning out a pool of scientists for national reconstruction.
